I would take that bet. In 5, 10 or 20 years electric vehicles will still vastly outnumber hydrogen powered vehicles.
We'll probably upgrade the charger to higher speed (Ionity already support 250+Kw) but what's the point?
As for the weight, do you know a Model 3 weight roughly as much as the BMW Series 3 (closest competitor)? https://carbuzz.com/compare/bmw-3-series-vs-tesla-model-3#ca...
It's cheaper, too: https://insideevs.com/features/517960/tesla-model3-bmw-3seri...
[Edit] Correcting myself, looks like Komatsu/Proterra are working on a bigger EV excavator. [1] I hope this becomes affordable because the noise reduction of electric would surely make my neighbors happy and I would love to not breath diesel exhaust.
